BMW M5 E60 (2005-2010) Valvetronic Catback Stainless Steel Exhaust System

Engineered for BMW M5 E60 (2005-2010) owners, this Valvetronic Catback Stainless Steel Exhaust System uncorks the S85B50 — BMW M's only series-production V10 M5 — with a T304 stainless catback. Ships with its own electronic control box and wireless remote — valve management is integrated during installation and afterward operated via the supplied remote. Manufactured in Europe and quality-controlled by BYC Performance.

The S85B50 V10 NA produces 507 hp with an 8,250 rpm redline — one of the highest-revving BMW M engines ever. This stainless catback removes the factory muffler restriction and reveals the V10's intake-driven character — noticeably fuller and more aggressive with the valve open, daily-friendly OEM+ tone with valve closed.

Stainless vs. Titanium — This Is Stainless

This product is the T304 stainless steel variant. A titanium variant is also offered for E60 in our catalog:

• T304 Stainless (this product): Durable, deeper sound tone, lifetime rust resistance, value option
• Grade 5 Titanium (separate E60 SKU): Noticeably lighter, sharper metallic note, heat-tint finish, premium price
• For weight reduction and premium aesthetic: titanium preferred
• For everyday durability and a deeper V10 note: stainless is ideal
